When your furnace is operating properly, it should provide warm air without making too much noise. While it’s normal to hear your furnace making noise as it turns on, other noises are showing your furnace requires immediate professional support.

Here are some of the most frequent furnace noises and what they can mean. If your furnace is making a weird noise, our friendly heating professionals are here to help with the best furnace repair in Albuquerque, New Mexico.

1. Furnace Making a Banging Noise

You might have a critical situation on your hands if you’re noticing your furnace making a banging noise. If your furnace is making a knocking noise, it may signal there could be a few problems. These range from gas building up in your furnace or a ductwork issue.

Banging Sounds Coming from Your Furnace

Your heating system becomes filthy over the years, so that’s why it’s critical to schedule routine furnace maintenance with I-Deal HVAC. One of the tasks our technicians do during this service is clean your furnace’s burners. When this component gets grubby, you might hear your furnace making a loud rumbling noise if ignition is delayed. The following gas buildup can crack your furnace’s heat exchanger, where natural gas changes into warm air. Any breaks in it can leak carbon monoxide, which is normally vented outside. This hazardous gas can be fatal in large concentrations.

If you’re hearing banging or knocking sounds coming from your furnace, I-Deal HVAC advises turning it off and reaching us at 505-445-1250. Excessive natural gas in your furnace or a fractured heat exchanger are critical issues that require immediate repairs.

Banging Sounds Coming from Your Ductwork

Your furnace uses ductwork to deliver hot air throughout your residence. If the ductwork wasn’t put in correctly or is getting dated, it can be noisy when your furnace runs. This might be the problem if your furnace makes a banging noise when it shuts off. Get in touch with I-Deal HVAC at 505-445-1250 and we’ll figure out the problem.

2. Furnace Making a Buzzing Noise

If you notice your furnace making a buzzing noise, don’t delay calling us. A buzzing sound often is telling you there’s an electrical problem, like with its transformer, blower motor or capacitor.

Your furnace relies on an internal transformer to work on the proper voltage. If wires or the box is loose, you could detect a low humming noise in the furnace when off. Your furnace also works with a blower motor, which moves heated or cooled air around your space, and a capacitor, which triggers the motor. If either of these components are fading, they will buzz when the furnace turns on.

3. Furnace Rattles

If your furnace is making a rattling noise, it could be the result of something minor, like an unfastened screw, or something serious, like a broken component. In either case, we advise shutting your furnace off and calling our heating professionals at 505-445-1250 for assistance.

4. Furnace Is Making a High-Pitched Squealing Sound

If your furnace makes a high-pitched noise, like squealing, when it’s heating, it’s trying to tell you it needs some TLC. If you’ve forgotten furnace maintenance the past few years, belts could be worn out or a bearing could need to be greased. We are aware that maintenance frequently slips your mind, but our pros can get your furnace running quietly again fast.

5. Furnace Makes a Whistling Sound Like Air Escaping

When you’re detecting your furnace making a whistling noise, it’s frequently the result of an air leak in your ductwork. You might also notice whistling while the furnace is running if a floor vent isn’t secure. If you’ve examined your vents but are still hearing sound, I-Deal HVAC can provide support. It’s essential to get loose ductwork fixed fast, as it can make comfort problems in your home and inflate your energy bills.

6. Furnace Making a Grinding Noise

It’s not a good sign if you hear your furnace making a grinding noise. This metal-on-metal racket typically means there’s an issue with your furnace’s blower. Switch off your furnace off promptly and contact our pros at 505-445-1250 for assistance.
